in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of a part of a cracker-machine to which our improvement has been applied, part being broken away. Fig. 2 is a plan view of a part of the same, partly in section, through the line 00 m, Fig. 1. Fig. 3 is a sectional end elevation of the same, taken through the line y Fig. 2.

The object of this-improvement is to provide cracker-machines constructed in such a manner that the bed-plate can be readily adjusted as the desired thickness of the sheet of dough or the wear of the cutters may require.

The invention relates to a cracker-machine constructed with its elastic bed-plate resting upon two eccentric rollers, so that by turning the said rollers the bed-plate can be adjusted with accuracy. The two eccentric rollers are provided with worm-wheels and a worm, so that the said eccentric rollers can be readily operated, as will be hereinafter fully described, and then claimed.

A represents the frame of a cracker-machine. B is the endless apron by which the sheet of dough is carried to the cutters, and which passes around rollers 0, one of which is shown in Figs. 1 and 2, journaled to the ends of the'frame A. Motion is given to the roller 0 from the drive-shaft D by gearing which is not shown in the drawings, as there is nothing new in its construction.

E are the feed-rollers from which the sheet of dough passes to the endless apron B, and which are driven from the roller 0 by a chain of gear-wheels, as indicated in dotted lines in Fig. 1.

To the drive shaft D are attached eccentrics F, with which are connected the lower ends of the rods G. The upper ends of the rods G are pivoted to the ends of the head-block H, which moves up and down between guides I,

attached to the frame A, and carries the cutters .T.

The part of the endless apron B upon which the cutting is done rests upon the bed-plate K, supported by rubber blocks L, to give it the necessary elasticity. The rubber blocks L rest upon a plate, M, which rests upon the faces of the eccentric rollers N, journaled in bearings 0, attached to the frame A. The

journals of the eccentric rollers N, at one side of the frame A, project, and to'them are attached worm-wheels P, which mesh into a' worm, Q, journaled in bearings attached to the frame A. The worm Q can be placed be tween the worm-wheels P, as illustrated in the drawings, or it can be placed beneath the said worm-wheels, as may be desired or convenient. The worm Q can be operated by a hand-wheel, R, attached to its end or connected with it by beveled gearwheels S T and a shaft, U, as the construction of the machine may render most convenient. The latter arrangement is illustrated in the drawings. \Vith this construction, by turning the worm Q the worm-wheels P and the eccentric rollers N will be turned to raise or lower the elastic bed-plate K. L M, as the thickness of the sheet of dough or the wear of the cutters may require.

A special advantage of this construction is that all parts of the bed-plate will be raised or lowered through exactly the same space, so

that the said bed-plate will always be level, and thus always in position for the cutters to operate properly upon it.

We are aware that elastic beds or plates in cracker-machines have heretofore been known, and elevated and lowered by means of a yoke and a single eccentric roller. \Ve employ two eccentric rollers, operated in opposite direc-' the action of one roller in carrying or forcing we claim as new and desire to secure by Let- 20 it in one direction is overcome by the action of tcrs Patent the other, operating in the opposite direction, In a cracker-machine, the combination,with when they are turned.

10 This construction also enables us to dispense and a single worm for turning both wheels and with the yoke, and makes the machine more rollers, whereby they are revolved in oppoo compact. It also renders the table entirely site directions, as shown, and for the purposes independent of the rollers. The rollers, by set forth. bearing under the table their entire length, 1 3
